BIGARD COVERING SYSTEM 3 Sheets-Sheet 3 Filed Jan. 4, 1946 fig 13 Patented Feb. 14, 1950 COVERING SYSTEM Andr Jules Eugene Louis Bigard, Paris, France Application January 4, 1946, Serial No. 638,954 In France October 17', 1944 Section 1, Public Law,690, August 8, 1946 Patent expires October 1'7, 1964 Claims, I (Cl. 108-40) Various forms of execution of the invention are t shown by way of example in the appended drawings.

Figure 1 is a top plan view of the tile.

Figure 2 is a cross-sectional view perpendicular to the slope.

Figure 3 is a sectional view in the direction of t the slope.

Figure 4 is a bottom perspective view of the butt-strap.

Figure 5 shows an assembly of four tiles with a butt-strap between both lower tiles, said butt-- strap being represented in chain lines between both upper tiles.

Figure 6 is a sectional view showing the side.

flanges of two adjacent tiles, the butt-strap being not in position. s

Figure 7 is "a cross-sectional view showing the butt-strap in position.

Figure '8 is a sectional view of the tiles show; ing, in the upper part, the flange and the placeoifi location of the butt-strap in chain lines and, in the lower part, how the butt-strap covers the flanges of the tiles.

Figure 9 is a sectional view showing how the butt-strap is hooked in its lower part in the tenon of the truss and how it is maintained in its upper part by the upper butt-strap.

Figure 10 is a sectional view showing rabbet panels making it possible to obtain smooth surfaces.

Figure 11 is a sectional view showing sheet metal panels hooked by lugs instead of tenons.

Figure 12 is a sectional view showing wood panels hoked by lugs instead of tenons.

Figure 13 shows a form of the lug substituted for the tenon.

Figure 14 shows a flat iron which is clamped between the lugs, and

Figure 15 shows a tile for a nook or valley with the tenon encased in the upper part of the tile.

2 In Figure 1 the places of the notch shown in dotted lines at I and 2 are to be noted.

Figure 2 shows a possible form of execution of the transversal covering with a tight joint 3 in right angles with the tenon 4, and other kind of covering being possible without departing from the scope and spirit of the. invention.

Figure 3 shows the profile of the tenon 4 or of the purlin on which the lower part of the tile is clamped. v I

On this figure it is to be noted that a clearance 5 exists between the upper edg e of the tile and the lower edge of the upper tile. Said clearance is at least equal to the amount of the re-entering abutment 6 of the half dovetailin order that the tile may be Islided between both tenons. The dotted line I indicates a possible recess in the tile outside the part resting on the trusses.

Referring now to Figures '4 to 9 of the drawings,

the tiles comprise .a side flange ll serving as a channel for the water and preventing the latter to creep into the space I: between both tiles and forming an expansion joint.

The butt-strap comprises a heel 13 which engages the space I Z between both adjacent tiles. Said heel comprises a bevelled part which is clamped between the tenon 15 and the common rafter of the truss. It comprises; furthermore, two flanges covering the edges "of the adjacent tiles. 1

In order that the heel j c'an be put in position it is necessary that a longitudinal clearance is available which is a little larger than theme-entering part of the half dovetail of the tenon. For preventing every dangerof infiltration a part i '1 provided in the rear of the butt-strap engages be-' tween both upper tileswhich show a suitable recess and in the front part a nose 8 which amply covers the whole.

Figure 10 shows a modification according to which the tiles instead of covering-one another by being superposed are encased by means of a rabbet HI. 7

Figures 11, 12', 13 and 14 show how the tenon can be substituted by a lug having the form shown in Figure 13.

Figure 11 shows an isothermal tile made of sheet metal. Said tile is formed of a frame made of suitably braced angle irons 20 and 2| and covered by an upper sheet metal piece 22 and a lower sheet metal piece 20, the hollow being filled with advantage with glass wool 24. The angle bars forming said frame are provided with holes for the passage of the lugs 25 to which the tile or the lap joint is hooked.

Finally, Figure 15 shows that in case a tile is ,t

to be bevelled for a nook, for instance, it is impossible to provide for the encasing of the tenon in the lower part; in this case it is necessarily 7 provided in the upper part of the tile at 30.

Iclaim: 1. In a roof construction a plurality ofspac ed parallel supporting members arranged in the direction of the slope of said roof; a' plurality .of

projecting tenons arranged along the upper faces of said supporting members and forming part thereof; a plurality of tiles placed on said supporting members so that each of them is supported by adjacent 1 members along opposite edges; and notches provided .at the" lower corners. of said tiles into which-- said projecting tenons fitso as tosup'port said tiles.

2. In a roof constructionaplurality of spaced parallel supporting me'mbers arranged in the direction of the slope of said roof a plurality of semi-dovetail-shaped tenons arranged along-the upper faces of said supporting members and forming part thereof, 'each of =said' semi-dovetail-shaped tenons having an upper supporting face forming an acute angle-with thecorresponding supporting member; a-plurality' of tiles placed on'said supporting members-so that each of them is'supported by adjacent members alon opposite edges; and notches provided at the lower corners of said tiles into which said projecting semidovetail-shaped tenons fit so ,as to supportwith said supporting faces said tiles.

' 3. In a roof construction a plurality of spaced parallel supporting members arranged in the di-= rection of the slope of said roof; ;a-plurality of semi-dovetail-shaped tenons arranged along the upper faces of said supporting. members and,

forming part thereof, each of said semi-dovetaib shaped tenons having an upper supporting face forming an acute angle with the corresponding supporting members; a plurality of tiles placed on said supporting members so that each of them is supported by adjacent members along opposite edges; and semi-dovetail-shaped. notches .provided at the lower corners of- 'said tiles andprovided each with a supporting notchface forming an acute angle withtthe innerface :of the tile, said notches being'arranged .so that said projecting semi-dovetail-shaped tenons fit into said notches contacting with theirsupporting faces said supporting notch faces of said tiles, so as to support said tiles; 7 1 t 4. In a roof-construction a plurality of spaced parallel supporting members arranged in the direction of the slope of said roof; a plurality of projecting tenons arranged along the upper faces of said supporting members and forming part thereof; a plurality of tiles placed on said supporting members so that each' of them is supported by adjacent members along opposite edges; notches provided at the lower corners of said tiles into which said projecting tenons fit so as to support said tiles; and a longitudinal recess along the lower edge of each of said tiles connecting said notches at the lower corners of the same, the thus formed lower edge portion of thetile'having a reduced thickness and serving as covering for the next lower tile.

5. In a roof construction a plurality of spaced parallel supporting members arranged in the direction of the slope of said roof; a plurality of projecting tenons arranged along the upper faces of said supporting members and forming part thereof; a plurality of tiles placed on said supporting members so that each of them is supported by adjacent members along opposite edges; notches provided at the lower corners of said tiles into which said projecting tenons fit so as to support said tiles; upwardly turned flanges along the supported edges of each of said tiles; and a removable covering member for covering saidprojecting flanges of adjacent tiles, said covering member having a T-shaped cross section and composed of a strip-shaped portion projecting between said flanges of said tiles and curved covering portions adapted to enclose the flanges of adjacent tiles, said strip-shaped portion of said covering member being provided at its upper end with a cut-out into which one of said tenons project.
